1. ## Line Segments Equation

How would I go about doing this one:

Find XY if WX = 1/3(XY)

your question was already answered here. Please do not double post, it is against the rules

3. Hello, Mr.Jiggyfly!

Just substitute into the equation . . .

We have: . $\underbrace{WX}_{\downarrow} \;=\;\frac{1}{3}\underbrace{(XY)}_{\downarrow}$
. . . . . . . $x + 2 \;=\;\frac{1}{3}(5x + 2)$

Solve for $x$ . . . then evaluate $5x+2$
